Robert Pattinson and FKA Twigs were spotted on a London night bus after partying on New Year's Eve.

The 'Twilight' star and 'Two Weeks' singer have been dating for several months and despite their high-profiles, opted to take the cheap method of transport home instead of forking out cash for a private car.

A source who spotted the famous couple on the double decker vehicle said: ''Rob was wearing his trademark scruffy beanie and Twigs was cuddled up in his arms on the top deck, dressed all in black. They looked adorable and blended in completely.''

The pair - who are believed to have spent Christmas together at the home of the musician's mother in Gloucestershire, south west England - welcomed in 2015 at Hackney hotspot, London Fields Brewery, in the English capital, where they partied at a £10-a-ticket celebration alongside 'Pyramids' singer Frank Ocean and 'Friends' star David Schwimmer.

Despite seemingly enjoying themselves at the trendy bash, the source said it looked like the musician - who released her debut album 'LP1' in 2014 - was feeling the effects of their party lifestyle afterwards as she napped on the shoulder of the famed actor as they made their way home.

They continued: ''Twigs looked like she was sleeping at one point - they'd clearly had a good time at the party.''
